At the distance of NGC 5128 ( Mpc) it is
possible to resolve globular clusters
with high resolution imaging from the ground,
thus allowing the globular cluster candidate selection primarily
through their morphological properties.
I report the discovery of 71 globular clusters in NGC 5128 on VLT UT1+FORS1
images, including the faintest members ()
known to date in this galaxy as well as in 5 previously-known clusters.
U- and V-band photometry has been measured for all the candidates and the
luminosity function, spanning
and , constructed.
These are the deepest globular cluster luminosity functions in an
elliptical galaxy determined so far.
The Kolmogorov-Smirnov statistics show that the
difference between the globular cluster luminosity functions
of NGC 5128 and the MW is not larger than
the difference between the ones of M 31 and the MW.
The ()0 color histogram shows a bimodal distribution.
For 23 globular clusters I obtained K-band
images with SOFI at the NTT in La Silla. Their positions
in the () vs. () color-color diagram
indicate that they are indeed old globular clusters.
Assuming that the globular clusters in NGC 5128 span a
similar age range as the ones in the Milky Way and adopting a linear fit
between the metallicity and ()0 color, the metal-rich clusters
peak at dex and the metal-poor ones peak at dex.
